BROOM-SHOULDER CUTTER.

SPECIFICATION forming part of Letters Patent No. 480,287, dated August 9, 1892.

Application filed January 30, 1892.

To all whom it may concern.-

Be it known that 1, WILLIAM F. SETTLE, a citizen of the United States, residing at Russellville, in the county of Logan and State of Kentucky, have invented a new and useful Broom-Shoulder Cutter, of which the following is a specification.

This invention relates to broom-machines; and it has for its object to provide a shouldercutting attachment for ordinary broom-wirin g machines which shall provide simple and efficient means for cutting shoulders large or small and at any desired angle to facilitate the securing the straw to the broom-handle and finishing off the inner ends of the straws, which is aided by the revolving broom. The cutting attachment trims the inner ends of the straws and greatly lessens the labor in broom manufacture. With this in view the invention contemplates an improved cutting attachment used in connection with ordinary broom-machines.

With these and many other objects in View, which will readily appear as the nature of the invention is better understood,the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated in the drawings, and claimed.

In the accompanying drawings, Figure 1 is a perspective View of the simpler form of cutting devices connected with the frame or table cated therein, the cutting-knives being illustrated in dotted lines as drawn out from the machine-table and swung against the broom. Fig. 2 is a similar view of a modification of the machine contemplating in a single construction the separate parts of the said simpler form in Fig. 1. Fig. 3 is a transverse sectional View showing part of one of the knife-rods of the simpler form of attachment. Fig. 4 is a similar view through the modified form. Fig. 5 is a detail in perspective of the modification showing the knife guide decached and the cutting-knives.

Referring to the accompanying drawings, A represents the frame or table of an ordinary broom-machine, which may be of any preferred construction. To one side of said frame or table A is attached the stationary attachment-plate B, suitably secured to said Serial No. 419,829. (No model.)

table and provided at each end with openings b, registering with corresponding openings in both sides of the frame and adapted to receive the sliding and rocking knife rods or shafts C, working through the table or frame and said plate and adapted to be slid out from said openings to adjust the knives carried thereon. The said attachment-plate B is provided with a central depending U- shaped portion 0, which projects below the plane of the opposite ends of said plate and which partially surrounds one of the openings 0 through the sides of the machine table or frame, and which receives the handle of the broom D, mounted therein and adapted to be rotated by the ordinary mechanism of the machine on which the attachment is used.

The broom is connected with the ordinary wiring devices, as will be apparent, and on account of the disposition of the openings 0 or, more properly speaking, bearings, in which the broom-handle is mounted, the same is rotated below the plane 'of the opposite ends of said plate. Mounted or carried upon one end of the front knife-rod O is the undercuttingknife E, which when not in use is adapted to stand in the vertical position illustrated in Fig. 1; but when used for cutting the shoulder in the broom-stock or trimming the ends of the straws off the same is grasped by the handle a and forced against the under side of the rotating broom-stock. A continued pressure on the knife causes a shoulder to be made on the broom and the straws quickly trimmed, and by adjusting the said knife to and from the machine-table, according to the width of the shoulder needed or where the same is to be cut, the same may be properly adjusted to the work. A securing-screw 6 may provide means for suitably securing the knife E to the rod. The rearmost shaft C carries upon the same side of the machinetable a swinging knife-plate F, having the opposite knife-guides f, receiving the sliding knife-shank F, working through said guides and carrying the overcutting-knife blade F which is adapted to be thrown in contact with the upper portion of the broom during rotation by grasping the handle end f. When not in use, the overcutting-knife member is slid toward the machine-frame and is supported in the position as shown in Fig. 1 by means of the supporting-pin f", but when in use is drawn from the machine-frame the requisite distance and is borne down upon the top of the broom, as illustrated in dotted lines in the same figure.

It may be readily seen that the described over and under cutting members of the attachment may be used independently of each other or jointly, the under knife making one out while the over knife makes an auxiliary cut above the under knife to aid the same in rapidly cutting the shoulder, each knife acting in an auxiliary capacity with respect to the other knife.

In lieu of the construction described, in which the knife members are separated from each other on opposite sides of the knifehandle, it may be preferred to employ the modification illustrated in Fig. 2 and other figures of the drawings, in which both the over and under cutting knife members are mounted in a single attachment. In such form, asillustrated in Fig. 2 and the transverse sectional and detail views of the same, the attachment-plate B is provided with a squared opening 0'', adjacent to the broom-handle opening and corresponding with similar openin gs in the machine-frame, said openings being adapted to receive the sliding rod 0, which is adapted to be slid in and out of the machine-frame. The outer or attachment end of the rod C" terminates in a securing-head G,having adjusting perforations g, by means of which the knife-head H may be adj ustably secured thereto. An adjusting-screw 0" works through the plate B into the perforation 0" and serves to hold the knife-rod O in any of its adjusted positions. The said knife.- guide head H comprises the parallel guideplates I, connected adjustably with each other at their upper and lower ends by means of the thumb-screws t', and between which ends are interposed packing-strips or washers 'L', which strips hold the said guide-plates I sufficiently apart to allow a space between said plates to accommodate the over cutting-knife J working therethrough. The said knife J is provided at one end with a handlej and at the other end with an upwardly-extending knob-grasp j, by means of which the said knife may be held tightly upon the revolving broom and worked back and forth through the guide-head like a saw to facilitate in cutting the shoulder on the broom, as will be apparent. The inner plate I is provided with an oifstanding securing-arm K, which is pivot-ally clamped to the rod-head G by means of the bolt 70, engaging the same and one of said perforations in said head and corresponding aligned perforations in the arm, and said arm is provided with a stop-lug To, which is adapted to strike against the top of the knife-carrying rod 0" when the guide-head H is in its vertical position, to allow the overcutting-knife to bear straight down upon the broom-stock. This connection allows the said knife-head to be adjusted at any desired angle with relation to the rod 0 to cut an angular or slanting shoulder on the broom or to bevel or trim off the inner ends of the straws.

Pivoted upon the outer plate I of the guide head is the undercutting single knife L,having the ordinary handle I, by means of which the said knife may be thrown up under and against the revolving broom, to be used either jointly with the knife J or independently, in the manner as previously described for the undercutting-knife member E. The moditied form of cutting attachment just described when not in use is also slid toward the machine-frame and against the same, as illustrated in the drawings, but when in use is drawn out to. suit the work. The packingstrips or washers not only serve to space the plates I, but also prevent the knife from becoming dull when allowed to touch the same. The knife working between said plates when not in use may be held tightly in position at either the top or bottom of the guide-head by tightening one of the clamping-screws '13, as will be apparent. The said knife is particularly adapted for cutting large shoulders on broad brooms, but is equally well adapted for other brooms.

The construction and many advantages of the herein-described cutting attachment are thought to be apparent without further description.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-- 1. In a cutting attachment for broom-machines, the combination, with the machine frame or table, of a sliding laterally-adjustable knife rod or shaft mounted in said frame and a separate swinging movable knife removably connected to the outer end of said rod, substantially as set forth.
